T rends in tobacco use are changing, and that’s good news forpublic health, according to the American Lung Association.

The public is becoming more aware of the health costs of tobaccouse, and more individuals are making the choice to be tobacco free.

Tobacco Use—A Serious Health Risk

According to the Surgeon General, tobacco use, particularly smok-ing, is the number one cause of preventable disease and death in

the United States. Because tobacco use has been linked to many healthrisks, the government requires that all tobacco products carry warninglabels. Avoiding all forms of tobacco can prevent many serious healthproblems. Still, every day some teens begin to smoke, chew, or diptobacco. Many people begin to use tobacco products thinking thatthey can quit whenever they want to. Tobacco use can be habit-form-ing, but like other chemical dependencies, it is treatable.

NicotineOne of the reasons that tobacco users find it difficult to quit is

that tobacco contains an , a substance that causesaddictive drug

Tobacco products, whichare made from the leavesof tobacco plants, containnicotine. Experts say thatnicotine is more addictivethan heroin or cocaine.Analyze the harmful physical and mental consequences of tobacco.

physiological or psychological dependence. All tobacco products con-tain , the addictive drug found in tobacco leaves. Nicotine isclassified as a —a drug that increases the action of thecentral nervous system, the heart, and other organs. Nicotine raisesblood pressure, increases heart rate, and contributes to heartdisease and stroke. Once addicted, people need more and moretobacco to satisfy the craving for nicotine.

Cigarette Smoke—A Toxic Mixture

Not only is tobacco addictive, but the smoke from burningtobacco is toxic. In 1992 the Environmental Protection

Agency classified environmental tobacco smoke, or secondhandsmoke, as a Group A carcinogen. This is the most dangerous class ofcarcinogen. A is a cancer-causing substance. Othercompounds in tobacco smoke are described below.

Tar and Carbon MonoxideCigarette smoke contains , a thick, sticky, dark fluid produced

when tobacco burns. As tar penetrates the smoker’s respiratorysystem, it destroys cilia, tiny hairlike structures that line the upperairways and protect against infection. Tar damages the alveoli, orair sacs, which absorb oxygen and rid the body of carbon dioxide.It also destroys lung tissue, making the lungs less able tofunction. Lungs damaged by smoking are more susceptibleto diseases such as bronchitis, pneumonia,emphysema, and cancer.

, anothercompound found in cigarettesmoke, is a colorless, odorless, andpoisonous gas that is taken up morereadily by the blood than oxygen.Carbon monoxide replaces oxygenin the blood, thereby depriving thetissues and cells of oxygen. It alsoincreases the risk of high bloodpressure, heart disease, and harden-ing of the arteries.

Harmful Effects of Pipes and Cigars

L ike smoking cigarettes, smoking pipes or cigars presents majorhealth risks. Cigars contain significantly more nicotine and

produce more tar and carbon monoxide than cigarettes do. Onecigar can contain as much nicotine as a pack of cigarettes. Pipe andcigar smokers have an increased risk of developing cancers of thelip, mouth, and throat.

• Bidis and clove cigarettescan contain up to seventimes as much nicotineand twice as much tar asregular cigarettes.

Cigarettes contain 43 known carcinogens, includingcyanide, formaldehyde, andarsenic. They also containpoisonous chemicals used in insecticides, paint, toiletcleaners, antifreeze, andexplosives. How can you usethis knowledge to help othersstay tobacco free?

Harmful Effects of Smokeless Tobacco

S is tobacco that is sniffed through the nose,held in the mouth, or chewed. These products are not a safe alter-

native to smoking. Like tobacco that is smoked, smokeless tobaccocontains nicotine in addition to 28 carcinogens, all of which areabsorbed into the blood through the mucous membranes and thedigestive tract.

Because smokeless tobacco is often held in the mouth for alength of time, it delivers both nicotine and carcinogens to thebody at levels that can be two to three times the amount deliveredby a single cigarette. As a result, people who chew eight to ten plugsof tobacco each day take in the same amount of nicotine as a two-pack-a-day smoker. Smokeless tobacco is as addictive as smokedtobacco. In addition, it irritates the mouth’s sensitive tissues, caus-ing , or thickened, white, leathery-looking spots on theinside of the mouth that can develop into oral cancer. Cancers of thethroat, larynx, esophagus, stomach, and pancreas are also morecommon among users of smokeless tobacco.

How Tobacco Affects the Body

For several decades health officials have warned the public aboutthe health risks of tobacco. The chemicals in tobacco products

can cause damage to many body systems. Figure 21.1 on page 543illustrates some of the effects of tobacco on the body.

Short-Term Effects of Tobacco UseSome effects of tobacco use can occur immediately after using the

product. Here are some of these short-term effects:

� Changes in brain chemistry. The addictive properties ofnicotine cause the body to crave more of the drug. The usermay experience withdrawal symptoms such as headaches,nervousness, and trembling as soon as 30 minutes after his orher last tobacco use.

� Increased respiration and heart rate. Breathing duringphysical activity becomes more difficult; and in some cases,nicotine may cause an irregular heart rate.

� Dulled taste buds and reduced appetite. Tobacco usersoften lose much of their ability to enjoy food.

� Bad breath and smelly hair, clothes, and skin. Theseunattractive effects may cause people to avoid the tobacco user.

Long-Term Effects of Tobacco UseOver time, tobacco use takes a serious toll on many body

systems, including the respiratory, cardiovascular, and digestive

HEALTH RISKS OF TOBACCOTobacco use damages several important body systems, causingsevere health problems that may result in death.

Nervous System• Addiction• Increased risk

of stroke

systems. The immune system is weakened, making the body morevulnerable to disease. Long-term tobacco use can lead to healthproblems such as:

� Chronic bronchitis. Repeated tobacco use can damage thecilia in the bronchi until the cilia no longer function. Thisleads to a buildup of tar in the lungs, causing chronic coughingand excessive mucus secretion.

� Emphysema. This is a disease that destroys the tiny air sacs in the lungs. The air sacs become less elastic, making it moredifficult for the lungs to absorb oxygen. A person withadvanced emphysema uses up to 80 percent of his or herenergy just to breathe.

� Lung cancer. When the cilia in the bronchi are destroyed,extra mucus cannot be expelled. Cancerous cells can grow inthese conditions, block the bronchi, and move to the lungs.Unless detected early, lung cancer causes death.

� Coronary heart disease and stroke. Nicotine constrictsblood vessels, which cuts down on circulation, or blood flow.Nicotine also contributes to plaque buildup in the bloodvessels, which can lead to hardened arteries, a condition calledarteriosclerosis. Arteries may become clogged, increasing therisk of heart attack and stroke. The risk of sudden death from

In sixth grade, Roni Dixon was hanging out with what she calls an

“older crowd.” She started smoking cigarettes in an effort to fit in.

Then something happened that changed Roni’s perspective. She

nearly passed out after a cross-country race at

school. “Mom always said I’d have to choose

between sports and smoking,” says Roni. She

was so frightened by her inability to breathe

that she vowed never to smoke again.

Roni not only kept her promise never to

smoke but began focusing on school and

volunteer work in the community. Today, she

belongs to 10 different organizations. “I want

people to know that low-income people in the

not-so-good communities can get good grades,

be active in programs, and go to college.”

Roni dreams of returning to her hometown

and helping kids turn their lives around. “If I could do it, they can too,”

she says. “It’s all about thinking positively and believing in yourself.”

“Mom alwayssaid I’d have tochoose betweensports andsmoking.”

heart disease is three times greater for smokers than fornonsmokers. A nonsmoker knows how to delay the onset ofand reduce the risk for potential health problems duringadulthood.

Other Consequences

Tobacco use brings many other serious consequences, espe-cially for teens.

� Legal consequences. Selling tobacco products to personsunder the age of 18 is illegal in all states. Schools prohibit theuse of tobacco products on school property, and a student maybe suspended or expelled for breaking these rules.

� Social consequences. Many people find secondhand smokeand the smell of tobacco offensive, so tobacco users may beexcluded from social gatherings.

� Financial consequences. Use of tobacco products can bevery expensive. Someone who smokes a pack of cigarettes a day can spend more than $2,000 each year just on cigarettes.According to a recent report, the total economic cost oftobacco use to taxpayers in the United States, includingmedical costs, is about $97 billion a year.

Choosing to Live Tobacco Free

Knowing the health risks of tobacco use has helped people makethe healthful decision to stay tobacco free.

Reduced Tobacco Use Among Teens

According to the Centers for Disease Control and Prevention(CDC), smoking rates among teens have fallen sharply in recent

years. Reports show that nationally 22 percent of high school stu-dents smoke. This is down from 36 percent in 1997. Some factorscontributing to this ongoing trend include:

� Antismoking campaigns. In 1998 tobacco companies and 46 states reached a legal settlement that restricted tobaccoadvertising and promotion. Tobacco companies are now requiredto fund ads that discourage young people from smoking.

� Financial cost. Tobacco use is expensive. Many teens find thatthey would rather spend their money on healthier alternatives.

� Societal pressures. Legislative acts have limited smoking in public places. More young people are growing up in anenvironment that is less tolerant of secondhand smoke.

� Family influence. Many teens avoid tobacco use becausetheir parents strongly disapprove of the use of tobacco products.

Benefits of Living Tobacco Free

People who have never used tobacco and people who have quitenjoy the many benefits of a tobacco-free lifestyle. Avoiding

tobacco lowers the risk of lung cancer, heart disease, and stroke. Itimproves cardiovascular endurance and lung function, whichincreases physical fitness and enhances athletic performance.

Living tobacco free has mental, emotional, and social benefits,too. Tobacco-free people have a sense of freedom because they knowthat they are not dependent on an addictive substance. They experience less stress because they don’t have to worry abouthealth-related problems caused by tobacco use. A tobacco-freelifestyle also helps a person look and feel better. Having higherenergy levels, healthier skin, fresher breath, and better-smellingclothes and hair increases confidence in social situations. Health-literate teens recognize that tobacco use can impact personal goals,educational opportunities, and occupational choices.

Strategies for Preventing Use of Tobacco

The best way to avoid the negative consequences of tobacco useis never to start using tobacco products. Nearly 90 percent of all

adult smokers started when they were teens, so if you avoid tobaccouse during middle school and high school, you are likely to staytobacco free throughout your life. A tobacco-free individ-ual knows strategies for health enhancement and riskreduction. Below are some strategies to help you stickto your decision to become and stay tobacco free.Health-literate teens know how the social environ-ment influences the health of the community.

� Choose friends who don’t use tobacco. Being aroundpeople who share your values and beliefs will strengthenyour commitment to lead a tobacco-free life.

� Avoid situations where tobaccoproducts may be used. By staying awayfrom such situations, you reduce thechance of being pressured to use tobacco.

� Practice and use refusal skills.Prepare in advance what you will say ifsomeone offers you tobacco. Your refusalmay be a simple “No thanks,” or youmay give a reason, such as, “No, I needto stay fit for the track competition.” Beassertive, and leave the situation if thepressure continues.

Why Some Teens Use Tobacco

In spite of the many benefits of a tobacco-free lifestyle, someteens choose not to resist the pressure to start smoking. Some teens

think that smoking will help them control their weight or cope intimes of stress and crisis. Other teens believe that smoking willmake them seem mature and independent. These beliefs are farfrom the truth about tobacco use. Because smoking reduces thebody’s capacity for physical activity, it may actually lead to weightgain. In addition, health problems and nicotine dependency willincrease the tobacco user’s stress level.

Other reasons for teen tobacco use are peer pressure and mediainfluences. Some teens try their first cigarette with a friend whoalready smokes. Other teens may try tobacco to imitate, or model,celebrities or other adults who smoke. Some teens are influenced byads that depict tobacco use as glamorous and sophisticated.

Being aware of these influences and being informed about theharmful effects of tobacco can help teens resist the pressure to usetobacco products. Teens who analyze these influences realize thatmost people who use tobacco products suffer from health problemsand wish they could quit the habit.

Reasons to Give Up Tobacco Use

Many teens who start using tobacco do decide to quit. Here arejust a few of the reasons they cite:

� They begin to have health problems, such as asthma orrespiratory infections.

� They have the desire, will, and commitment to stop.

� They realize how expensive the habit is.

� They realize that using tobacco can lead to other riskybehaviors, such as the use of alcohol and other drugs.

� They find it difficult to purchase tobacco products becauseselling tobacco products to persons under the age of 18 isillegal in all 50 states.

� They realize the damaging effects of secondhand smoke anddon’t want to harm their families and friends.

Stopping the Addiction Cycle

M illions of people have succeeded in their effort to quit tobaccouse. Overcoming nicotine addiction can be difficult, but it’s

not impossible. Most people who stop using tobacco will experiencesymptoms of , the process that occurs in thebody when nicotine, an addictive drug, is no longer used. The cravings

� In three days breathingbecomes easier as lungcapacity increases.

� Within two weeks to threemonths lungs function up to30 percent better.

� Within one to nine monthslung cilia regrow, and cough-ing, sinus congestion, andshortness of breath decrease.

� In one year the risk ofcoronary heart disease is cutin half.

� In five years the risk of lungcancer and cancers of themouth, throat, and esophagusis reduced by 50 percent.Stroke risk is also decreased.

� In ten years the risk of cancerof the bladder, kidney, cervix,and pancreas decreases.

and discomfort caused by these symptoms are temporary, andsmokers trying to quit should remember that success will lead tobetter health.

WithdrawalSymptoms of nicotine withdrawal include irritability, difficulty

concentrating, anxiety, sleep disturbance, and cravings for tobacco.To relieve the symptoms, some people use a ,a product that delivers small amounts of nicotine into the user’s systemwhile he or she is trying to give up the tobacco habit. Many nicotinesubstitutes are available, including gum, patches, nasal sprays, andinhalers. Nicotine gum products are OTC products; the other nico-tine substitutes require a doctor’s prescription.

Help a Friend STOP Using TobaccoStudies have shown that most people who try to quit have a greater success rate if they have support from others. A smoke-free advocate knows positive ways toinfluence others to make positive choices. Use the STOP approach to help someonestop using tobacco.

Write a plan that addresses eachof the STOP guidelines. If youhave a family member or a friendwho uses tobacco, create theplan for that person, or work witha classmate who knows someonewho uses tobacco. Make surethat your plan contains messagesthat promote the health benefitsof stopping tobacco use. Considerthe person, and tailor the plan tothat person’s needs and interests.

ACTIVITYACTIVITY

A C T I V I T YShow concern. Approach the person in a caring,

nonjudgmental manner. Use “I” messages to let the personknow that you care about his or her health.

Take time to plan. Putting a plan on paper makes it easier toset objectives. You may need to help the person create aphysical activity program. Set a date to quit, locate formaltobacco cessation programs, and devise strategies to copewith tobacco cravings.

Offer support. Put the plan into action. For example, youmight bring the person sugarless gum. Ride a bike, shoothoops, or take a walk together to help him or her get physicalactivity. Arrange to attend a class together to learn relaxationtechniques.

P romote success. Let the person know that you are proud ofhim or her for quitting. Celebrate each week of abstinence. Ifthe person relapses, continue to encourage him or her. Keep intouch with the person after he or she has quit.

Effects of Smoke on Nonsmokers

Environmental tobacco smoke from cigarettes and cigarscontains more than 4,000 different chemical com-

pounds, 43 of which are identified as carcinogens. Inhalingthis smoke either by smoking or by breathing in ETS bringsthese carcinogens into the body. ETS affects people of allages, causing eye irritation, headaches, ear infections, andcoughing. It worsens asthma conditions and other respira-tory problems. Every year 3,000 people are diagnosed withlung cancer caused by secondhand smoke.

Effects of Smoke on Unborn Children and Infants

Choosing to live tobacco free is one of the best things apregnant woman can do to make sure that her baby will beborn healthy. Smoking during pregnancy can seriouslyharm the developing fetus. Nicotine passes through theplacenta, constricting the blood vessels of the fetus.Carbon monoxide reduces the oxygen levels in themother’s and the fetus’s blood. These negative effectsincrease the risk of impaired fetal growth, miscarriage, pre-natal death, premature delivery, low birth weight, deformi-ties, and stillbirths. The infant may also suffer from growthand developmental problems throughout early childhood.

Babies of smokers are two and a half times more likely to die ofsudden infant death syndrome (SIDS). One study found that nearly60 percent of all SIDS cases could be prevented if babies and preg-nant females were protected from tobacco smoke. Infants exposedto ETS have an increased risk of asthma, tonsillitis, and respiratorytract infections.

Effects of Smoke on Young ChildrenYoung children are also particularly sensitive to environmental

tobacco smoke. Children of smokers are nearly twice as likely to bein poor health as those of nonsmokers. Consider these facts:

� Children of smokers tend to have a higher incidence of sorethroats, ear infections, and upper respiratory problems thanchildren of nonsmokers.

� Children who live with smokers have double the risk ofdeveloping lung cancer than children of nonsmokers.

Because children learn by example, it’s not surprising that chil-dren of smokers are nearly three times as likely to smoke aschildren of nonsmokers. Being a positive role model is anothergood reason to make the choice to be tobacco free.

Parents protect the healthof their children by stayingtobacco free. Analyze theharmful effects of tobaccoon the fetus.

Communication: AvoidingEnvironmental Tobacco Smoke

You can protect your health and the health of others by asking smokers not to light up in your presence. Read the scenarios below, and practice communication skills by stating politerequests for a smoke-free environment.

Situation 1You are at a wedding rehearsal dinner with relatives.Your favorite cousin, whom you haven’t seen for along time, is seated next to you. As you begin catchingup on family news, your cousin lights a cigarette.

Situation 2You and your friends have been waiting for 30 minutesto be seated in a restaurant. A table becomes availablein the smoking section, where several people aresmoking heavily. Your friends want to take it.

Reducing Your Risks

What can you do to protect yourself from ETS? If you and yourfamily want your home to be smoke free, politely ask visitors

to refrain from smoking inside. If someone in your householdsmokes, open windows to allow fresh air to circulate, and requestthat certain rooms remain smoke free. Consider using air cleaners tohelp remove contaminants from the air. If you are visiting a homein which someone smokes, go outside or to another room. Ask to open the window slightly to provide fresh air. Suggest meetingelsewhere, such as in your home or at a library. In restaurants andother public places, request seating in a nonsmoking area. If nosmoke-free area is available, go to another restaurant.

Toward a Smoke-Free Society

A s people realize that smoking causes diseases and harms notonly their own health but also the health of others, the drive to

become a smoke-free society increases. Today’s consumer under-stands how public health policies and government regulations influ-ence health conditions. Many states have taken steps to prohibitsmoking in all public buildings and private workplaces. Many peo-ple are promoting laws that would ban smoking and eliminate ETSin public places such as restaurants, civic buildings, business offices,and lobbies. Laws prohibiting the sale of tobacco products to minorsare being strictly enforced. Tobacco licenses are being revoked whenstores sell tobacco products to people under the age of 18.

Statewide antismokingcampaigns are effective inreducing smoking. For exam-ple, the number of smokers in California was reduced by 16 percent in the first four years of that state’s campaign. The number ofsmokers in Massachusettswas reduced by 20 percent.

Increasingly, the law is taking into consideration the rights of thenonsmoker. Certain states have successfully sued tobacco companiesto recover the cost of treating tobacco-related diseases.

program called Healthy People 2010 to promote health and preventdisease nationwide.

Recently “Not for Sale” commercials began air-ing on MTV and Nickelodeon.

Over the last decade, the audience meant tobenefit from that message has been growing.Every day, 6,000 teen-agers try smoking for thefirst time and 1,200 Americans die from tobacco-related disease. Studies show that nearly 80 per-cent of regular smokers light up their firstcigarette by their 18th birthday.

Andy Berndt doesn’t think that lectures abouthealth risks that can occur years down the roadwill convince teens to stop smoking. “No adultcan make kids understand the issues like anotherkid,” he says. “If we educate other kids about allthe ways the tobacco industry is trying to deceivethem, we’ll win the war.”

“Do you want to be deceived?” yells thespeaker at the podium, 17-year-old

Andy Berndt. “No!” roar the more than 700teenage antismoking activists who have packedNew Jersey’s Liberty Science Center. The shoutseems loud enough to be heard all the wayacross the Hudson River—at Philip Morris’sManhattan headquarters. That’s where thisprotest is aimed: at the giant cigarette companiesthat, the activists believe, target teen smokers.

A Stand Against SmokingEach of the teens in the auditorium wears a

white T-shirt declaring “Not for Sale.” Thismeans that they can’t be bought by the millionsof dollars tobacco companies spend every dayadvertising cigarettes. They’ve come here todeclare something else—the creation of astatewide teen antitobacco group called REBEL(Reaching Everyone by Exposing Lies). It’s thenewest in a pack of teen-led antismoking organi-zations starting up nationwide. Their mission: toteach teens not just about the health risks ofsmoking, but about the tactics tobacco compa-nies use to hook young people on their products.
